Visible and Infrared Thermal Imaging Spectrometer

Led by CNR-IASF, Rome, Italy, and Observatoire de Paris, France

VIRTIS will be able to study the composition of the lower atmosphere between 40 kilometres altitude and the surface. It will track the clouds in both ultraviolet and infrared wavelengths and allow scientists to study atmospheric dynamics at different altitudes.

VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) is an imaging spectrometer that operates in the near ultraviolet, visible and infrared parts of the electromagnetic spectrum (0.25 to 5µm wavelength range). The instrument has a variety of operating modes that cover a range of observations from pure, high-resolution spectrometry to spectro-imaging.

VIRTIS allows the analysis of all layers of the atmosphere and the clouds therein, the making of surface temperature measurements and the study of surface / atmosphere interaction phenomena.
